Abstract
An improved grappling device for a material handling apparatus, including one or more fingers which may be mounted on the material handling apparatus. The fingers are storable to a non-use position on the rear side of the bucket of a material handling apparatus and retractable to an operating position in front of the bucket of a material handling apparatus by means of hydraulic power. When in use, the fingers cooperates with the material handling apparatus and enables an operator to manipulate a wider range of loads.
Claims12
A grappling device connectable to a material handling apparatus, comprising:
- an arm member having first and second ends, wherein said first end of said arm member is pivotally connectable to said material handling apparatus;
- one or more fingers pivotally connected on said second end of said arm member;
- a first hydraulic piston and cylinder assembly having first and second ends, wherein said first end of said first hydraulic assembly is pivotally connectable to said material handling apparatus, and said second end of said first hydraulic assembly is connected to said second end of said arm member, whereby actuation of said first hydraulic assembly controls the movement of said arm between a working position and a storage position;
- a second hydraulic piston and cylinder assembly having first and second ends, wherein said first end of said second hydraulic assembly is connectable to said material handling apparatus and said second end of said second hydraulic assembly is pivotally connected to said material handling apparatus, whereby actuation of said second hydraulic assembly moves said arm member in a forwardly and rearwardly direction;
- a push rod having first and second ends, wherein said first end of said push rod is connectable to said material handling apparatus and said second end of said push rod is pivotally connected to said fingers, whereby when said arm is rotated rearwardly to a storage position, said push rod rotates said fingers into a storage position;
- and
- a biasing means attached to said fingers and said arm member for urging said fingers to a normally open position.
